Breaking the Belle

IX:The Point Of No Return

The birds merrily sang to one another in the trees above Rarity’s head. The sun beamed down on Ponyville, just another idyllic summer day. The saddlebags on her flanks bounced with each step as she meandered from store to store, stocking up on important goods. The bell above the door chimed as Rarity entered her last stop on her list. The Post Office. The clerk looked up at the white unicorn that approached.

“Hello Miss Rarity,” called out the clerk, grinning and waving.

“Hello there my Dearest! It’s a simply gorgeous day, is it not?” Rarity cooed, approaching the desk, suave as ever.

“It certainly is!”

The clerk leaned down beneath his counter, rummaging round until he found the large package he was looking for, labelled with Rarity’s name. Lifting it atop the counter, Rarity thanked him.

“So, Miss Rarity, tell me, is this little parcel something for your sister? Are you getting in on this ‘Pet’ idea Twilight’s been telling everyone about?”

Rarity smiled as she watched the excited expression grow on his face. Why hide it now?

“Yes it is, Dear. Why do you ask?”

She expected some kind of chastisement.

“Because I’ve seen so much ‘special gear’ being posted here to Ponyville residents over the last few months! Stuff from all over Equestria! Ornate jewelry from The Crystal Empire, industrial gear from Yak-Yakistan, even some strange perverse ‘toys’ of some sort from Changeling Hives and the Dragon Lands! Ponies are really getting into the Princess’ ideas!”

Rarity smiled, delicately placing the parcel in her saddlebag.

“Well, she is a Princess, after all, you can’t help but love her!”

With that, she turned back towards the door, waving the clerk goodbye, before heading back home.

* * * * *

The door of the Boutique creaked open. Rarity stepped inside, shutting the door again with her magic, before letting her saddlebags slide from her rump and drop unceremoniously to the floor. She let out a sigh of relief as the spell she’d cast over her body dissipated, her vast shaft and testes reappearing between her legs. Sure, she could just magically rid herself of the cock and recreate it upon returning home, but she liked the idea of hiding such a tool in plain sight. It made her feel powerful.

Leaving her bags by the door, Rarity trotted through the house towards the stairwell. Down she went, stopping in front of the second door, listening for a second before pushing it open. There she was, her little pet. Sat up against the far wall where she’d been left, the gear still locked tight against her, the two little vibrators still working their magic. The poor foal was a mess, her mane scruffy, her face bright red, her hind legs twitching madly as her body tried again and again to cum, with some cruel external force blocking it every time.

With a flash of her horn, the two vibrators shut off, sliding carefully from her holes. Another flash and all the locks that had held her in place were freed: the straitjacket slipping away, the spreader bar unlocking, the ball gag and blindfold slipping from her face. The latex still clung to her fur and her horn, but at this point Sweetie didn’t care about that in the slightest. The little filly dashed over to her Mistress, tightly hugging her leg, though her own wobbling legs gave out beneath her once or twice on the way.

“Thank you so much for letting me out, R- Mistress! Thank you thank you thank you!”

She started to feverishly kiss her Sister’s hoof, lost in desperate adoration. Only when Rarity patted her head did she stop, looking up into her eyes.

“M-Mistress, how long was I in here for? My body feels so sensitive…”

“Long enough to learn your lesson, hopefully," Rarity replied, "...and long enough to realize how much your Mistress cares for you. All those hot dinners didn’t cook themselves.”

Sweetie began to squirm awkwardly, clearly trying to find a way to ask more of her sister.

“Can I-... I mean, can Pet get out of this latex too?”

“I’ve already been generous enough to let you out of here so soon… don’t push it. Come with me. I have work to do.”

The two unicorns ascended the stairs, stopping in the tailor room. Rarity took her seat at the sewing machine, and began to bark instructions at Sweetie to grab materials and tools from around the room. Much to her pleasant surprise, Sweetie actually did so, running (albeit slowly atop her wobbly legs) around the room, getting the supplies she was instructed to. The array of materials began to pile up on Rarity’s desk, until everything she needed was together. Setting to work, she occasionally looked over her shoulder to see Sweetie sat awkwardly at her side, unsure whether or not she was free to leave or if she had more to do for her Mistress.

Rarity felt her cock twitch as she looked at the gorgeous, latex-clad foal.

“Come now Sweetie, slide yourself under the desk. Mistress needs to concentrate on her work.”

She didn’t need to say it twice. The little filly maneuvered herself under the desk, between Rarity’s legs, her face flushing as the rapidly engorging tip brushed against her cheek. Watching the cock rapidly stiffen, she took the tip into her mouth, holding the head for a few seconds, running her tongue along the various ridges and bumps of its profile. It caught Rarity off guard when that little tongue poked against her urethra, slowly stretching her open. As she fed the first piece of fabric into the sewing machine, she guided her Pet’s head forward with her magic, gently encouraging the filly to sink the cock deeper and deeper into her throat. The mare was still rather slow and nervous around her Mistress’ cock, which was a shame. However, Rarity could sense that Sweetie was almost completely converted. She just needed one more hard push to send her over the edge, and from that point on Rarity would really have her own perfect Pet, the poster child for this new culture. Rarity would be the talk of the town.

She continued to work on the outfit, though she found herself really rather distracted. It wasn’t so much the physical sensations of Sweetie’s warm throat tightly holding her cock, it was the thought of how close this little filly was to finally being her Pet. She couldn’t wait anymore. She had to finish the process.

Sliding her chair back, she climbed onto her hooves, picking Sweetie up and throwing her over her shoulder. In an unexpected feat of strength, she carried the mare up the stairs, stopping outside Sweetie’s door. She barged the door open, stepping inside and throwing Sweetie onto the bed. The foal sank down into the soft duvet and mattress, looking up at her Sister with a mixture of nerves and undeniable lustful excitement. Without so much as a word Rarity leapt up onto the bed, standing over her Pet. Her massive, fully engorged cock slapped down on her belly, dragging backwards towards her nether regions, the head coming to rest against her pussy lips.

She had denied Sweetie the sensations of her mammoth cock inside her vagina for all this time. Waiting for the right moment. And the right moment was now.

Sweetie opened her mouth to speak, but Rarity slammed her hips forwards at full speed, burying her entire length in Sweetie’s pussy. She yelped in shock, stunned as her abdomen bulged outwards as her Mistress’ cock made room for itself inside her. Sweetie mewled in pathetic delight as Rarity withdrew all but her tip, before slamming the full length forwards once more. Out bulged her abdomen again, rapidly flattening out as Rarity withdrew.

Rarity dropped down from her hind legs, pinning her full weight across Sweetie’s body as she relentlessly bred her vagina. The entire bed rocked back and forth with each powerful thrust, dull thuds filling the room as the headboard smashed against the wall. Sweetie’s tongue lolled from her open mouth, moaning loudly to herself like a feral animal, urgently shifting her hooves from gripping her Mistress’ sides to digging into the duvet they laid on. The latex would squeak occasionally as Rarity’s body rubbed against her sisters, adding to the chaos of sounds emanating from the pair.

As Rarity rocked back and forth, breathing heavily to herself, she leant down next to Sweetie’s ear, pressing her mouth against Sweetie’s neck. She held there as she thrust, before pulling away to look at the heavy love bite she’d left behind. As suddenly as the whole event had started though, she suddenly pulled out, slapping her vast, slick cock down on Sweetie’s belly again.

“..N-now,” Rarity gasped between deep breaths. “Be a good little Pet and close your eyes. Mistress has a surprise for you.”

Partially out of respect, partially out of an urgent want to continue the sex, Sweetie clamped her eyes shut, taking in a deep breath as she felt a sheet of latex positioned over her muzzle and eyes. She listened as Rarity rummaged through Sweetie’s cupboards, before evidently finding what she’d been looking for. Whatever it was, it was apparent that her older sister had the confidence to hide sex toys in Sweetie’s room for later use. The filly found that both humiliating and deeply arousing. She tried to listen for more sounds, but they’d stopped for the most part. The only noises she heard now were those of Rarity climbing back onto the bed. Her cock pushed against her pussy again.

The sheet of latex was thrown to one side. Sweetie looked down to see what Rarity had got, but she needn’t have looked. She felt it soon enough. Around her cock she’d strapped a large, bump covered band, effectively tripling the thickness of her already impressive medial ring. And there, teasing against her ass, was a thick strapon attached below her ‘real’ cock. The thing was an all black cylinder with no features, just a tapered end. Whilst the dildo was a good half the length of Rarity’s cock, it was easily twice as thick.

As Rarity pushed her cock deeper into Sweetie’s vagina, she slowed as the tip of the dildo met her asshole. She drenched it in copious amounts of lube, and the numerous anal sessions the two had had over time helped her asshole open up rather quickly. The mare gasped as both the cocks lodged themselves inside her, eventually bottoming out as Rarity’s crotch smacked her buttocks. Back she went, the dildo popping free of her asshole as more and more of her cock slid out. Back in she went, the dildo pressing past her puckering asshole.

As she fell back into her pattern, the original speed quickly returned. Rarity dropped back down to completely pin her sister, basking in the little gasps and moans she let out every time her dildo pulled free of her ass, leaving her little ponut to wink and pulse with excitement until she pushed back in. The unicorn whispered into her Pet’s ear.

“You know, my Pet, the magic I can wield is so much more powerful than you’d ever have thought. These balls of mine are actually inert, my magic seed could never impregnate a mare. Or at least, that’s the way it once was. But you know I have friends in high places. Even as we speak dear Twilight is developing a fertility potion to allow inert seed to become potent again. Maybe, if you’re a good little Pet,” She teasingly slowed, before slamming her hips forward again, “...I’ll take the potion, once it is finished. You would like that, wouldn’t you? To be knocked up by your own Sister? Your own Mistress?”

Rarity pulled back to look her Sister in the eye. Her face blushed profusely, her eyelids twitched, and her eyes struggled to focus on Rarity's, but she still managed to nod eagerly. It was time. Her balls had begun to twitch in anticipation as her need to climax built. Continuing to thrust, but still picking up speed, Rarity looked down at her sister again.

"Do you want to cum, Pet?"

Sweetie urgently nodded, almost surprised she would ever be allowed such sweet release.

“Then tell me, who am I?”

"You're my Mistress!"

Good start.

"And who are you?"

"I'm your Pet!"

Getting better…

"And what are you now?"

"I'm Mistress' object, that only lives to serve her!"

"...Good girl."

And with that, Rarity’s horn flashed, undoing the collar that had been locked round her neck all this time. With the magical barrier down, Sweetie’s body could release the orgasm - the orgasm it had been desperate to release ever since she went into the cell, for nearly a week now. As she did so, Rarity forced her cock as deep into Sweetie as it could physically go, that wonderful bulge reforming in her abdomen.

The two began to cum at the same time.

Both mares screamed out in bliss as Rarity’s seed launched from her cock, painting Sweetie’s womb white with spunk. Very quickly the high powered excess began to fire out from her pussy, splattering back messily over Rarity’s crotch and heavy ballsack. As they did, Sweetie’s head lurched backwards, her back arching as her own orgasm started. Cum launched up from her pussy, soaking into Rarity’s coat, and slicking her cock. The jets were accompanied by her moans and screams, massive for such a little mare. Incomprehensible sounds and words tumbled from her mouth as her legs twitched madly, each powerful spray of cum sending her body rocking like a boat in a storm. Rarity’s explosion of seed continued as well, her thick cock holding most of the spunk inside her hungry womb, watching as her belly began slowly expanding to accommodate the incredible load.

Rarity was surprised when her orgasm began to peter out first. Her powerful loads became a dribble as the last of her spunk left her body, but Sweetie’s orgasm continued. As Rarity pulled out, some of the errant spunk splattered against her chin, one shot even clipping the ceiling.

She really was pent up.

Taking a deep breath, Rarity stepped towards the bedroom door, ready to wash herself and rest up. But before she did, she stopped and turned, watching Sweetie as her orgasm finally started to subside. The exhausted filly moaned and gurgled to herself, her whole body shaking as seed cascaded from her gaping pussy. Most of the words that left her mouth were entirely unintelligible, but Rarity managed to make out a few of them:

“Thank…”

“...you…”

“...Mistress.”

It was done.
